Ostrich (defense)
Due to its prehistoric looks and sizehere as Wmany great tales regarding the ostriches ways of natural defenses have been mytholoical. the head in the sand being foremost of falsehoods is in fact a digestive process/gathering pebbles to grind foods such as roots berries, aand an occasionally cricket. Another miscostrued act, kicking is actually more of a scare tacktic than a readiness to battle technique if forced to take a stance against a predator (Cheetas,Leopards, and Jackals) it can deliver a kick hard en ough to break bones, they tend to refrain from the use all together on multiple hunters due to slow and clumsy recovery leaving them very weak and unbalanced. Their main predator the cheetah has the right tools neededto compete with the Ostriches great speed 75-80kmh, And 50-55kmh for up to an hour it relies on open flat areas an drareley takes to the water getting it through eating moist vegitation. Their overgrown and eyes have developed for the wide and clear view you might see through binoculars, but with two competely seperate but 120 times that of a human eye. Therefore other predators usually pass the long distanse attemt unless their are young or injured animals available. despite the cheetas speed, it lack in numbers and need to stay healthy to survive as solitary animal. If coronted face to face at a stand off the Cheetah will usually choose self preservation and return to the wary and usually lone bird hours later when because it was sought after by a predator, it will be pushed from the group for up to a day, it is thought that the others have figured over time that leaving one vulnerable is is of more safety to the healthiest birds. However if the ostich chooses his stance while the large cat is still in pursuit feeling he may connect is generally done by young bird without the knoledg that at a full run the cheetah capable of a 13-18m high up to 35m in length long Jugular piercing leap hadn't had a chance to even kick the cat for some 30-35 yards making the attempt rather futile in most circum stances. At up to thirty chickks to one mother and 4-5 mothers per male they rely heavily on breeding for the survival of the species. After all they have been around during the dinasour age making it a resourceful and attentive creature rather than having the size or fight of the Water buffalo, it runs but both do what they do right with approximate succesful suvival rate at 98% —Preceding unsigned comment added by 198.236.58.29 (talk • contribs) 23:32, 9 December 2004‎‎ (UTC)

Eyesize?
Surely more than just whales have ostriches beat for eyesize (though not of land animals) because squid eyes are gigantic. —Preceding unsigned comment added by 12.47.38.130 (talk • contribs)

Giraffes must have the largest eyes of land mammals, but I don't know how large. The runner up is the horse, with smaller eyes than an ostrich. Giant squid eye size has been exaggerated, but they are the largest in the animal kingdom: the largest measured eyball was 18 cm (7 in.) in diameter, with a possible maximum of 20 cm (8 in.) for the largest females.

weight correction
The article says the eggs can weigh 1.3kg, then goes on to say the average weight is 1.4kg. This needs to be corrected if anyone is familiar with egg mass.

--Victoria h 05:39, 4 February 2006 (UTC)

Well, based on a couple of studies on domesticated birds I found on the web, the average ostrich egg weighs 1.44 kg (3 lb 2¾ oz), with dimensions of 155 × 128 mm (6.10 × 5.04 in). The heaviest egg was 2.35 kg (5 lb 3 oz), layed on a Chinese ostrich farm. I don't know it's dimensions, but with typical proportions they should have been 182 × 151 mm (7.17 × 5.94 in). An egg of 2.222 kg (4 lb 14.38 oz) from a Polish farm measured 190 × 140 mm (7.48 × 5.51 in). The lightest weight I've seen was 755 g (1 lb 10.63 oz), suggesting dimensions of 125 × 103 mm (4.92 × 4.06 in) --Anshelm &#39;77 17:28, 5 July 2006 (UTC)

Evolution
I just removed the section on evolution (removed text appears below). The paragraph implies that there is some particularly significant similarity between ostriches and velociraptors, which simply isn't the case. Now I think about it, I suppose there might be a case for comparing ostriches to a much broader group of birdlike dinosaurs (the problem is, velociraptor is very specific, and ostriches more closely resemble other (non-carnivorous) birdlike dinosaurs), but I don't feel qualified to write that, so I'll leave it to someone else. I removed the section because it seems to me that as it stands all but the first line is misleading and therefore worse than useless. --Tremolo 00:36, 20 July 2006 (UTC)

Removed text: Evolution

The ostrich is the largest member of the extant ratites.

The ostrich resemble velociraptors, though their ancestral phylogenetic homologies are probably too difficult to match or even locate. Another possibility is that their phenotypic similarities (i.e. quick running, shape of body) are a result of convergent evolutionary inheritances that were advantageous for their environments, that did not arise from the same branch point in phylogenetics or from horizontal gene transfer.

Subspecies
If someone knows how the subspecies differ, please add that information as well. AxelBoldt 20:38, 26 Sep 2004 (UTC)


 * "The ostriches in Arabia and South-East Asia were hunted to extinction by the middle of the 20th century."


 * Er... are we sure that isn't southwest Asia? I may be wrong, but I've never heard of a Vietnamese ostrich. I assume it's an error, but without any definitive knowledge either way, I'm loath to change it. 129.2.211.72 05:07, 4 Oct 2004 (UTC)


 * Indeed so. But you might be interested to hear that there actually may have been Vietnamese ostriches (albeit only in the far north of that country). There was the Asian Ostrich which ranged all over Asia north of the Himalayas and the Caucasus and down southeastwards all over China, and it may have been a subspecies of the African Ostrich (the bones are more similar to those of the present bird than to any other fossil ostriches). It was well known to early humans, as ostrich cavepaintings and motifs on pottery from prehistoric China indicate. This bird went extinct some time in the Early Holocene (i.e. in the millennia following the end of the last ice age). Dysmorodrepanis 14:13, 6 October 2006 (UTC)

text illegible (small) in distribution map graphic
In the "taxobox" graphic showing present-day range on map, the names of subspecies are too small/unclear to be legible without enlarging image. I have not a lot of Wikipedia experience and no experience editing nature articles so I did not want to boldly make a size change since the taxobox width might be standard. I did look at the Birds project page and the example of the taxobox there did not include such tiny text as on this page. but perhaps this is an issue that needs to be discussed at a level higher than that of an article. Maybe it is considered OK to have to open graphics in a separate window in order to see text on charts etc? but i just thought I would point this out. Wichienmaat 03:17, 1 April 2007 (UTC)
 * I upped the image size, it's a bit more legible now. The problem being the width affects the length which affects the box size which can throw off the arrangement of pictures in the article itself.  The article is pretty picture-heavy and it's hard to get them all to line up nicely, but it seems to be OK as is.  That being said, if others feel like changing it further, I'm happy to see their ideas.  WLU 19:33, 1 April 2007 (UTC)

Species Status
If the current consensus is that the Somali Ostrich is a distinct species, Why does the article not reflect this? There is a short mention of the concept, but other than that, the article treats them both as one (example: the Taxobox mentions Struthio camelus but not Struthio molybdophanes). The Taxobox should go to Genus level, but not species level (rather, mentioning both species underneath instead). - 01:22, 20 May 2007 (UTC)

Froot Loops
Is the trivia on a box of breakfast cereal really considered to be a valid citation? -Dayv 15:25, 25 May 2007 (UTC)


 * Yes.

Struthio
If 'struthio camelus' means camel-sparrow, then struthio means sparrow? I find this weird since all 'struthio' words refer to the ostrich (struthiomimus, the ostrich-shaped dinosaur, and struthiolaria, the ostrich-foot mollusc) 23:26, 10 August 2007 ‎‎‎(UTC)‎

Reproduction
Isn't it true that the ostrich is one of the rare birds with a penis? If so, that should be put in the reproduction section. —Preceding unsigned comment added by 12.47.38.130 (talk • contribs)

Yes, we should add that in as well because it is true. Ostrich's are one of the rare birds out there that have a penis. I also know that Ostrich penises are used as an aphrodisiac and also heard that Ostrich's can have sexual intercourse up to 10 times a day. —Preceding unsigned comment added by 211.136.74.16 (talk • contribs)

Usage of Ostrich Feathers in Industry
Under the section "Ostriches and Humans" I would like to see added:

OSTRICH FEATHER DUSTERS —The preceding unsigned comment was added by Physche (talk • contribs).

In addition to the function of the Ostrich feather in clothing, costumes, decorations etc., it might be noted that one of the most useful contributions of the Ostrich feather to industry is its use in feather dusters. The original South African Ostrich Feather Dusters were invented in Johannesburg, South Africa by missionary, broom factory manager, Harry S. Beckner in 1903.

The first Ostrich Feather Dusters were wound on broom handles using the foot powered kick winder and the same wire used to attach broom straw. Ostrich feathers were sorted for quality, color and length before being wound in three layers to the handle. The first layer was wound with the feathers curving inward to hide the head of the handle. The second two layers were wound curving outward to give it a full figure and its trademark flower shape.

The First Ostrich Feather Duster Company in the United States was formed in 1913 by Harry S. Beckner and his brother George Beckner in Athol Massachusetts and has survived till this day as the Beckner Feather Duster Company under the care of George Beckner's great granddaughter, Margret Fish Rempher. Today the largest manufacturer of Ostrich Feather Dusters is Texas Feathers (TxF)which is located in Arlington Texas.

Young apprentices still use the manual kick winder to learn the trade of building the hand crafted Ostrich Feather Duster. However, to expedite the manufacturing process, factories now allow veteran craftsman to use electric powered winders to build the duster. Building an Ostrich feather duster can be a dangerous. The wire is under tension that is strong enough to sever a finger if it were to get caught between the handle and the wire.

The Ostrich feather is unique in its durability, softness and flexibility which accounts for the success of the Ostrich feather duster over the last 100 years. Because the feather does not zipper together it is prone to developing a static charge which actually attracts and holds dust which can then be shaken out or washed off. Because of its similar makeup to human hair, care of the ostrich feather requires only an occasional shampoo and towel or air dry.

Nutritional extra eggs
W. R. Ogilvie-Grant (1921) Guide to the gallery of birds. Pat 1. British Museum. (2nd Edn) (available on www.archive.org) says this about Ostrich egg laying: "The hens belonging to one male lay their eggs in the same nest, which is a shallow excavation dug in the sand. As many as thirty eggs are sometimes deposited in the pit, and many more are dropped around which are said to serve as food for the newly-hatched young. The contents of an egg are equal to about two dozen hen's eggs." Nutritional eggs are seen in frogs for instance - the Bromeliad frogs - perhaps there is some newer material supporting or denying this old idea. Shyamal (talk) 01:49, 15 February 2008 (UTC)

Brain size
I wonder what's the brain size of an ostrich. I heard Jack Hanna on Larry King say "as small as a grain of sand", which cannot possibly be true! Snapple caps say "smaller than their eye", which sounds plausible considering their small head with huge eyes :) -- and they look so smart with those huge intelligent eyes :)

Having visited 'Ostrich World', a nature park which specifies in ostriches, I have found that an ostrich's brain is the size of a pea. However I do not have any evidence to back this up. jammi_f 21:13, 26 October 2006 (UTC)

I was just watching an episode of Dirty Jobs where he went to an ostrich farm. There, the farmer claimed that their brains were the size of walnuts. Of course, I did not fact check this, but thought I'd throw it out there. It was the second episode of the second season, "Ostrich Farmer," if anyone cares.

Number of eggs a year
Anyone have a reliable source for the number of eggs laid a year? Various random sites on the web say anywhere from 10-100 which seems like quite a range. -Ravedave (talk) 01:17, 7 January 2008 (UTC)

Answer: The reason for reports of such variability in egg production is the nutrition the birds, their environment and management. Domesticated ostrich when nutritionally supported, maintained under good management systems and in the correct environment, genetically are proven to have a capacity to lay in excess of 80 eggs per season and in some cases producing in excess of 100 eggs. Currently the average on the large commercial farms is around 60 eggs/hen per season. There are a number of studies reporting this. One available on line can be found at. In the wild the hens will lay until there are sufficient eggs in the nest to incubate, hatch and rear. Hegaldi (talk) 10:44, 18 February 2009 (UTC)

Not the relatively smallest egg
Actually, the smallest bird egg in relation to the female's size is that of the Emperor Penguin (Aptenodytes forsteri) at 1.4 % (egg c. 400 g/14 oz, female c. 28 kg/62 lb), whereas the Ostrich's figure is said to be 1.7 % (egg 1.44 kg/3 lb 3 oz on average, suggesting a 85 kg/187 lb average for the female). The Emu (Dromaius novaehollandiae) also has the Ostrich beat at 1.5 %.

I'm not absolutely sure, where Cassowaries (Casuariidae) stand on this... Based on scarce bits of information, the egg of the Southern Cassowary (Casuarius casuarius) is c. 7 % larger (140 x 90 mm/5.51 x 3.54 in) than an Emu's egg (135 x 90 mm/5.31 x 3.54 in), the bird itself being c. 19 % heavier (65 kg/143 lb versus 54 kg/120 lb max. weight). Anshelm &#39;77

Update: I found an average of 580 g (20½ oz) for Southern Cassowary egg, 1.23 % of an average female of 47 kg (104 lb). Admittedly poor sources, but the figures are consistent with the ranges from more reliable sources. Also, for the Emperor Penguin I found an average egg weight of 440 g (15½ oz, Lynch 1997), 1.49 % of an average 29.5 kg (65 lb, Dunning 2nd ed 2007) female. Northern Cassowary may have relatively smaller eggs still, but I didn't find any info; the eggs of Dwarf Cassowary are relatively larger. So one of the two large cassowaries appears to be the recordholder, or at least they have relatively smaller eggs than the species this record is usually credited with. --Anshelm &#39;77 (talk) 04:03, 14 March 2009 (UTC)

Surviving eggs
Under "Reproduction" we have this: "The survival rate is low for the eggs. with an average of one per nest surviving." It should be clarified if that means only that many hatch, or if that many reach adulthood. --Preston McConkie (talk • contribs) 08:34, 20 July 2009 (UTC)

Range
I wonder if there is an inconsistency on the page about the range. There is an image of two Ostriches with a caption which indicates the presence of wild Ostriches at the Cape of Good Hope, but the range map in the infobox indicates no Ostriches anywhere near this region.

Predators?

Growth rate
According to the article, "At sexual maturity (two to four years), male Ostriches can be from 1.8 to 2.8 metres (5 ft 11 in to 9 ft 2 in) in height,[5] while female Ostriches range from 1.7 to 2 metres (5 ft 7 in to 6 ft 7 in). During the first year of life, chicks grow about 25 centimetres (10 in) per month." This is internally inconsistent. Growth of 10 inches per month for a year would require the ostrich to be at least 10 feet tall by the age of 1 year (or, using the 25 centimetres per month, 3 metres), which is taller than the upper range of adult male height reached at 2 - 4 years.

"Considered to be?"
Er... The text saying that the ostrich is "considered" the largest bird. Is there a certain precedent I'm missing? Is there a lesser-known bird that actually IS larger, but the ostrich gets all the credit? Is there a school of thought that uses a different bird-measurement system? Either it is the largest bird or it isn't; I don't think there's room for consideration here. Ergo, I'm removing the ambiguity. Feel free to change it if I'm actually wrong. Nevah 23:06, 2 August 2006 (UTC)


 * Some people insist that a few New Zealand moa survive. In that very unlikely case, the ostrich would not be the largest bird.  So "considered" might be an appropriate word. Cranston Lamont 23:15, 4 September 2006 (UTC)


 * Has no bearing on the matter, because the moa survival issue is always concerned just with the smaller species. The giant Dinornis were long gone by 1500 AD. Dysmorodrepanis 14:14, 6 October 2006 (UTC)

New material on burying head in sand myth
I have reverted this because I integrated the material into the existing paragraphs and citation format. I also added another citation for the "looks like a mound of earth in the heat haze" because "todayilearned" does not appear to be a reliable source. Since it's still being readded, I've added an allusion to the point as a possible explanation of the head in the sand myth, and made that a repeated reference; but that raises the need to replace that with a reliable source.

 * I've never seen that except in some field note reports and texts aimed at trained specialists - and the intention there is to indicate precisely which species has been observed or is discussed. In an article aimed at a general, wider readership - or in a popular book about different kinds of birds - it seems out of place. Decapitalize! Strausszek (talk) 09:18, 29 April 2010 (UTC)
 * I just did an informal survey of Wikipedia bird articles and the complete common name of the bird was capitalized throughout. It seems strange to me, but it does appear to be the Wikipedia standard.--Davefoc (talk) 05:47, 13 May 2012 (UTC)
 * It's certainly a strange convention, but I respect it. I also appreciate this as a bit of pedantic academia that I can drop into casual conversation for maximum pretentiousness.  Silly scientists. --Darsha  —Preceding undated comment added 18:20, 28 March 2013 (UTC)

Cats
I noticed this edit, clearly GF by both very experienced editors, but it raises a discussion point. For some time, it's been an unofficial practice to consolidate country/state/province cats into larger units, as User:LittleJerry did. For really widespread species, the list can otherwise get to over 100 country cats. However, there is no policy basis for doing this, and User:Yngvadottir was within her rights to revert the change. She suggested that I raised the point here, so that interested editors can express a preference regarding whether to have country cats or larger units.  Jimfbleak -  talk to me?  15:02, 7 May 2014 (UTC)
 * I prefer widespread species be categorized into regions rather than countries. The Ostrich category section with bloated with too many countries. I think those many be more suited for the subspecies. LittleJerry (talk) 15:14, 7 May 2014 (UTC)

Dinos
Should there be a comment on how Ostriches and other ratites are thought to be direct descendants of Dinosaurs, and of the first fossil record? 70.142.36.210 02:27, 9 February 2006 (UTC)

Personally I think ostriches have descended from dinosaurs. More precisely, the velociraptor. I mean have you ever taken a good look at those feet?? — Preceding unsigned comment added by 165.138.12.250 (talk) 15:21, 13 January 2015 (UTC)

Lead image
I recently replaced the lead image showing a single male with an image showing both male and female. This has now been replaced with another image and an edit summary stating my previous edit was because it is more "important" to have an image showing sexual dichotomy than a high resolution image. This is not the reasoning behind my edit. I made the edit because I thought the image of 2 ostriches was "better". This is of course a matter of opinion. I felt it was "better" to have a good quality "close up" image that showed sexual dimorphism, rather than a high resolution image of only a male, somewhat in the distance. Being a high definition image does not make an image better per se, it is also whether it is representative of the subject matter. The current image that replaced my edit is an extremely good one and I thank the editor for making this.__DrChrissy (talk) 14:56, 1 February 2015 (UTC)
 * The lead image change from the single bird to the one with both sexes was taken in good spirit, which is why the new image was added to Commons and then to this page. It is always important for people adding photographs to read and understand what the editors are thinking because what photographers think is a good photograph may not be relevant to the article. So, thank you for stating the reason for change in the edit summary. Cheers. :-) -- ~y (talk) 16:25, 1 February 2015 (UTC)
 * Yes, thanks for providing another image that shows both male and female birds, . I was puzzled by your change of image, especially since you gave no reason; I didn't even notice it was a sharper image. Since this article is clearly watched by a lot of experts, I left it to others to either query the change or revert it, but I would urge you to follow your own advice and explain your reasoning in the edit summary. Yngvadottir (talk) 18:58, 1 February 2015 (UTC)
 * I apologize if I caused any trouble. I should have mentioned the reason in the first change, which to me was obvious but clearly not in retrospect. -- ~y (talk) 20:53, 1 February 2015 (UTC)

Distribution
The section currently contains the following sourced line:


 *  They rarely go above 100 m (330 ft)

While the cited reference is an appropriate reliable source, the claim seems rather weird. I don't have access the source however to figure out what's wrong here.

And why is the whole thing weird? I've hardly ever heard of any land based animal being restricted to an altitude of below 100m. More importantly probably 90% of the distribution range shown on the map consists of regions above 100m. So could somebody check the source to see what's actually written there?--Kmhkmh (talk) 09:58, 17 May 2015 (UTC)
 * P.S. The original edition of the source (Grzimek), wich I can access, doesn't contain that claim.--Kmhkmh (talk) 10:10, 17 May 2015 (UTC)

North African subspecies conservation status
The text about the North African subspecies (camelus camelus) features the statement, "leading some to consider it Critically Endangered". The given source (http://www.cites.org/eng/app/appendices.php) does however not make this claim, indeed it does not appear to mention any subspecies at all. Thiis information has been faithfully copied into North African ostrich too (without any source, which is why I was trying to verify it). Any info on this, or another source?-- Elmidae (talk) 13:11, 4 May 2015 (UTC)
 * This was because an editor had randomly changed the citation to one that did not support the information. I have now corrected it (see this, with WP:WAYBACK because the page had died since then). 62.107.210.198 (talk) 22:20, 12 May 2016 (UTC)

Hi. Can you modify this file or create a new? What happens is that  S. c. molybdophanes  is recognized as a distinct species. Thank you, --Jr JL (talk) 23:20, 20 June 2016 (UTC)

 * The image is called "Struthio camelus distribution" but with new classification, it show too to S. molybdophanes. Ref. as species itis, Clemets checklist, Catalogue of Life, IOC, ZooNomen, BirdLife, original publication. --Jr JL (talk) 21:04, 23 June 2016 (UTC)

Communication
Although there is mention of mating rituals, there seems to be lacking information on the sounds they can produce and the circumstances when they produce a particular type of sound. 76.10.128.192 (talk) 23:36, 2 August 2016 (UTC)

"one _or_ two", or "one _of_ two"
From the intro description, first sentence. Is the common ostrich either one _or_ two species of large flightless birds, or is the ostrich either one _of_ two species of large flightless birds? — Preceding unsigned comment added by 167.102.227.254 (talk) 14:04, 13 December 2016 (UTC)


 * If I understand, the two possible species would be S. calemus and S. molybdophanes (Somali), yet it appears that recent research would have determined the second to be separate (although still of the same Struthio genus). Thus I have the impression that the author really intended "or" in this case.  In either case, it's probably possible to make the paragraph less ambiguous... 76.10.128.192 (talk) 22:27, 15 December 2016 (UTC)

Temperature Conversion
When talking about a temperature interval, you cannot convert between Celsius and Fahrenheit by interpreting the interval as a raw temperature and converting it. The interval temperature needs to be multiplied or divided by 9/5. The article mentioned that the Ostrich often lives in environments with a difference of as much as 40 degrees Celsius between day and night. This is equivalent to 72 degrees Fahrenheit, not 100 degrees Fahrenheit. I've changed it accordingly.67.245.69.244 (talk) 03:32, 3 January 2017 (UTC)


 * The conversion from C to F is x 9/5 + 32. Don't leave off the latter term. The template does it correctly. See Fahrenheit. -- Elmidae (talk · contribs) 07:38, 3 January 2017 (UTC)

pursued by a predator or chased by a predator
Jameel the Saluki (talk) wrote: You have recently made a change to the Ostrich article where 'pursued' was changed to 'chased' with the explanation ""pursued" by a predator -> "chased" Use plain English - readability counts". I have done a search on the usage of the terms, and from what I can find they are considered equally plain English and equally readable. What evidence do you have for your claim that chase is more appropriate for a Wikipedia article, and in particular for the context used? Your explanation seems very odd to me.

_________________________________

Let's see the context: "When being chased by a predator, they have been known to reach speeds in excess of 70 km/h (43 mph)..." IMO "When being pursued by a predator" is imprecise. Unlike "chase", "pursued" does not suggest such high speed. Besides, according to Google: "chased by helicopters"   31k  books: 301 "pursued by helicopters" 10k  books: 223

But helicopters can fly at a very slow speed, so let's take a better example:

"chased by F-16" 3k  books: 8 "pursued by F-16" 7k  books: 1

My conclusion - you may be right. So if you are absolutely sure, then do whatever you want. Or... I will do it myself. Ok, done. Regards :-) 85.193.240.37 (talk) 20:38, 15 January 2017 (UTC)


 * FWIW - I prefer "pursued" but for no strong reason. DrChrissy (talk) 21:20, 15 January 2017 (UTC)
 * Your opinion is important to me. Thanks. 85.193.240.37 (talk) 01:37, 16 January 2017 (UTC)
 * I had no opinion either way as to whether chased or pursued should be used. But I didn't want some ideas floating around about the choice between pursue and chase that were not true, becoming urban legend, and then restricting the number of words which could be used in Wikipedia unnecessarily. I would like to comment that in Australian English pursue has the connotation of being more persistent with a goal in mind, than chase. Pursuit is a more frequently used term, and almost used to refer to high speed chases. Chase has a mild connotation of playfulness, fun, and childishness. The lion chased the ostrich is more likely to be used by children for this reason. And pursued more likely to be used by adults, but perhaps depending on the intended meaning. In the particular context of the article neither pursue or chase are more preferable IMO as it is the speed to the ostrich that is the focus of the information. Jameel the Saluki (talk) 14:22, 16 January 2017 (UTC)


 * Wow, it sounds like an expert opinion. I wonder how much of this applies to American English? 85.193.240.37 (talk) 07:25, 17 January 2017 (UTC)


 * We could always avoid this terminology problem and use the word "hunted". DrChrissy (talk) 23:24, 16 January 2017 (UTC)
 * Of course, you do realize that hunting is a much broader category than pursuing. 85.193.240.37 (talk) 07:25, 17 January 2017 (UTC)
 * Yes, of course I do. You might want to take a look at my user page and see how many articles I have created on animal behaviour. DrChrissy (talk) 20:40, 17 January 2017 (UTC)

Lead
The first paragraph of the lead reads horribly and makes no sense. It refers to the species S. camelus then immediately talks about both species of Struthio as if they were both the subject of the article, which is clearly not the case. It should read something like: "The common ostrich (Struthio camelus) is one of two species of birds that are referred to as ostriches. The Somali ostrich (S. molybdopanes), formerly a subspecies of the common ostrich, was recognized as a distinct species in 2014. The two species are the only living members of the genus Struthio, which is part of the ratite family." 2001:569:7821:500:18A2:FBE2:63BB:18C6 (talk) 06:07, 7 June 2018 (UTC)
